In reply to:yea i wouldent really know, is it more senstitive than testicles? Yeah, much more sensitive. As was mentioned, the head of the penis is the most sensitive, as is the underside of the penis just below the head, where the frenulum is. These two areas are by far the most sensitive parts of the male body. Uncut guys have more sensitive penis heads (glans) than circumcised guys. In an uncut guy, the penis head is on the same sensitivity scale as the clitoris (i.e. direct stimulation can be almost painful its so sensitive). Compared to the testicles, if the penis head is say a "10" on a sensitivity scale of 0-10, then the testicles are maybe a "3". At least for me anyway. I mean the testicles are somewhat sensitive to touch, and they feel good to be massaged, but I'll never reach orgasm from just having my balls massaged.
